The correct option about squaring the binomial is that B. The student is wrong. There is a missing term.
<h3>How to use binomial theorem?</h3>
We want to square a binomial and using pascal's triangle in binomial theorem, we know that; (x + a)² will follow the pattern;
1x²a⁰ + 2a¹x¹ + 1x⁰a²
Thus, we can say that the expression (x + 3)² will give us;
x² + 2(3x) + 9a²
= x² + 6x + a²
Thus, we can say that the correct option about squaring the binomial is that B. The student is wrong. There is a missing term.
Complete Question is;
A student is instructed to square a binomial, and gets the result shown. Choose the correct description of the student's work. (x + 3)² = x² + 9 Choose the correct answer below.
A. The student is wrong. You cannot square a binomial, only monomials.
B. The student is wrong. There is a missing term.
C. The student is correct. Each given term is squared.
D. The student is wrong. The student should add the threes instead of multiplying them.

Answer:
1/4
Step-by-step explanation:
the x decreases by 1 the y decreases by 4
Answer: 3
Step-by-step explanation:
So for me, how I would do it is move the variables and numbers to one side. So we have the equation 3x-3=2/5x+7. So you would subtract 2/5x to the left side and add 3 to the right side. The equation will then turn out to be 3x-2/5x=7+3. Much more easier right? So just simplify both side, and you will get 13/5x=10. In order to isolate x, you have to divide 13/5 in both side, leaving x= 3 11/13 or 50/13. You can always plug the answer back in to double check :)
